The effects of anthropogenic global environmental change on biotic and abiotic processes have been reported in marine systems across the world. This global change has manifested in marine systems through altered oceanographic, biogeochemical and hydrological mechanisms that regulate marine system structure and functioning at different spatial and temporal scales. The multi-scale study of climate change in marine systems is further complicated by the connectivity in space, time and levels of biological organisation inherent in marine systems. For example, understanding climate induced shifts in: species range distributions (e.g., movement of tropical species into warm temperate regions), migration behaviour of anadromous, catadromus and amphidromus species between coastal environments and the ocean, or the dispersal range of plankton with altered currents all require scientists to conduct research and integrate knowledge across multiple scales and between different disciplines. The objective of this session is to integrate scientific knowledge of climate induced change on marine systems through the presentation of innovative research and technologies covering multiple spatial, temporal and biological scales from laboratory to global analysis and biological scales including individual cells and species to ecosystems. In addition to showcasing the state of marine climate research across multiple scales and disciplines, the session will discuss the possible future development of interdisciplinary climate change science in marine systems.
